A primary stat of 30 is suggested. If your main stat isn't high enough, you'll see the following message:

"Dude, we could get in SO much trouble if the cops found out we were letting underage kids drink here... Piss off."

(It is recommended that you have at least 30 <mainstat> to adventure here.)

If you're disguised as one of them, you get a different set of adventures. Although all non-disguised adventures have the same name, there appear to be three different ones, which can be distinguished by adventure text and monster drops.
